Abstract
The present invention creates detailed 2D images from 3D sets of angiographic data. First, a 3D set of angiographic data is acquired. Next, one determines from which perspective they wish to view the 3D data. After the perspective is selected, for each pixel in the 2D image to be created, an imaginary ray is extended through the 3D data set, according to the perspective from which the 2D image is being rendered. For each ray, the n most intense data points intersected by that ray are selected and summed together. Finally, the 2D image is created on a pixel by pixel basis, with each pixel being displayed according to the sum of the n most data points intersected by the ray associated with that pixel.
